I've been doing double alternating tabatas since starting the hybrid program. It's worked well since it's similar to couplet workouts like Fran, Elizabeth, and Diane, but your time is fixed at 8 minutes. Rather than trying to max out reps in every round, try to get the highest tabata score (at least x reps for each round). I've done:

18 (-20%) less reps all day, but with significantly more intensity. If you are already a sub 10 minute Fran'er, you should have somewhat similar times on this one, but there's a little more emphasis on ATP/CP and glyco here.

I think "Ganty Fran" needs to be designated a new named workout!
